machines, and particularly to the thread carriers and the means forsupporting and controlling the same. In Letters Patent No.

1,105,452, issued to me July 28, 1914, there is shown a form of threadcarrier having a roller at its inner end and a roller at its outer endby which the carrier is supported at both its inner and its outer endsupon positlvely driven pairs of rollers mounted on a revolving frame.One of the principal objects of this invention is to eliminate the innerpair of supporting rollers altogether and the positive drive of theouter rollers, and to take the weight off the outer pair of supportingrollers which are used in the present invention merely to drive thethread carrier in its circular path about the machine. The roller at theinner end of the thread carrier in my new construction runs on themargin of a disk which is preferably rotary and travels in the oppositedirection to the thread carrier and in the same direction as the strandswhichare passed over and under the thread carriers.

These and other features of the invention will be hereinafter more fullydescribed and particularly pointed out in the claims.

In the accompanying drawings which show one embodiment of the invention,

Figure 1 is a vertical section of such parts of a braiding machine asare necessary to illustrate the invention; v

Fig. 2 is a plan view, partly broken away, of certain of, the partsshown in Fig. and

Fig. 3 is an elevation of the outer end of one of the thread-masscarriers.

For a description of the general type of machine to which ble, referencemay be had to the aforesald patent, and it will only be necessary in thepresent specification to describe such parts the mvention is app1icaofthe machineas will serve to make clear a the novel features and theirrelation to the machine as a whole.

Referring to the drawings, 1 represents the frame of the machine,preferably made spider shaped and provided with a central hub 2 whichsupports a central tubular shaft 3, at the top of which the fabric isformed. The shaft 3 is surrounded by a sleeve 4, which is rotatable onthe shaft 3 and has secured to it a bevel gear 5, which rotates on theupper face of the hub 21 The fabric passes down through the hollow shaft3 to an idler roller 6 mounted on hub, 2, and thence passes to thetake-up mechanism (not shown). A driving-shaft 7, journaled in bearingbracket 8, secured to a ring 9 which forms part-ofthe frame, is providedat its inner end with a pinion 10 which meshes with bevel gear 5. I

Upon sleeve 4, above the bevel gear 5, is the revolving frame 11 whichsupports the strand guides (not shown), and is revoluble on sleeve 4.The frame 11, which may be termed the main revolving frame, is providedwith a bevel gear 12 on its under side engaging pinion 10. Thus theparts carried by frame 11, and those carried by sleeve 4, to which gear5 is secured, are caused to revolve in opposite directions.

Above the frame 11, is a disk 13, fast to sleeve 4, to which are securedconcentric annular rims 14, 15 and 16 connected by radial arms 17 theinner 14 being mounted on disk '13. In each of the segmental spacesbetween rims 15 and 16, there is journaled a pair of idler rollers 18and 19 for driving. the thread carriers hereinafter described. The disk13 with its rims and radial arms may be termed the roller frame.

Another disk 20 is mountedto revolve on hollow shaft 3 above sleeve 4.The disk 20 is provided with a bevel gear 21 on its under side and thedisk 13 is provided with a bevel gear 22 on its upper side. Bevelpinions 23, mounted on a bracket 24 fixed to the hollow shaft 3., workbetween gears 21 and 22 causing the disk 20 to be rotated in theopposite direction to disk 13 and the thread carriers driven thereby,and in the same direction as the strand guides (not shown) mounted onthe revolving frame 11.

Thus the disk 20 moves in'the same direction with the strands t andprevents rubbing and chafing of the strands, while the rollers 27 rollfreely over the strands. For certain classes of work, and in small sizemachines it will be found possible to mount the disk 20 stationary onthe shaft 3.-

A series of thread carriers 25, each carrying a cop or mass of thread26, are mounted in the several segmental spaces between rims 1A and andarms 17. At the inner end of the frame of each thread carrier is asupporting roller 27 which rests on disk 20. At the outer end of thethread carrier frame are a pair of rollers 28, mounted in a horizontalplane and running in a groove 29 in frame 11. Said rollers 28 bothsupport the outer end of the thread carrier and take the centrifugalthrust as the carriers revolve. Another roller 30, mounted in a verticalplane at the outer end of the thread carrier frame, extends betweenrollers 18 and 19 Q (Fig. 3). Thethre'ad carriers are driven fromsleeve4, through disk 13, and rollers 18, 19, engaging rollers 30, saidrollers permitting the strands from the strand guides to be passed underthe carriers and above @the rollers 18, 19, as the strands are car'-rled over and under. the thread. carriers.

The weight of the outer ends of the thread carriers is not supported bythe rollers 18,19,

but by rollers 28 runmng in groove 29, and the rollers 18, 19, ,merelydrive the-thread carriers. The outer end of each thread car- 1 rierframe is also provided on its upper side with another roller 31, lyingin a horizontal plane and running between the frame 11 and a downwardlyextending flange 'or guard 40 ring 32 secured to frame 11. Roller 31acts in conjunction with rollers 28 to resist centrifugal thrust andcooperates with guard ring 32 to prevent the thread carrier from beingdislodged inwardly from its position.

The threads 25 from the thread mass 276, and the strands t which arepassed over and under the thread carrier, all'extend to the bushing 33,at the top of the hollow shaft 3, where the fabric isformed. I claim: 7e
